Earlier this month, it became known that the US Air Force's aerial drones had been infected with malware. It didn't blow them up or anything, but it was embarrassing for the Air Force nonetheless.
It's even more embarrassing now.
According to an "anonymous defence official" speaking with the Associated Press, via Wired, the type of malware plaguing the aircraft and logging their user's keystrokes "is routinely used to steal log-in and password data from people who gamble or play games like Mafia Wars online."
If correct, that explains how the malware got onto the drone's networks. What it doesn't explain is what US Air Force crews were doing using military computers to either play Facebook games or gamble!
